To be fair, these sorts of political consultants are all dirtbags to some extent.
Of greater concern to me are the establishment types flocking to his campaign. Those people are real parasites, and can inflict permanent damage.
McCain’s Campaign Manager didn’t even vote for him.
They’ll flock to someone else if that someone else polls better. The neverTrumpers(tm) are just going with who they think can beat Trump. They ain’t the sharpest knives in the drawer.
